Measurement of $D^{\ast }$-meson triggered correlations in p+p collisions at RHIC

Abstract

We report the preliminary results of the azimuthal correlations between $D^{\ast \pm }$ mesons and charged hadrons ($D^{\ast }$-h) measured by the STAR experiment in proton+proton collisions at $\sqrt{s}$ = 500 GeV. Results at mid-rapidity in the transverse-momentum range 8 $\le$ $p_T^{D^{\ast }}$ $\le$ 20 GeV/$c$ are compared with light hadron triggered correlations (h-h) and PYTHIA predictions. We also present an exploratory study of azimuthal correlations between $D^{\ast +}$ and $D^{\ast -}$ mesons in p+p collisions. The prospects of measuring heavy-flavor triggered correlations in heavy-ion collisions at RHIC energies are also discussed.
